Shoot low there sheriff...were riding Shetlands.
That supposed vagrent beef you talk has to be USDA inspected at the last plant ( Argentina as You allege ) to get into the next plant for any processing.
For example you cannot take meat from a State inspected plant and bring that into a Federal inspected plant for further processing.
Perhaps google up the list:
Importing meat from foreign usda inspected plants.
BTW, the us exports a lot more beef and pork than is imported.
